Say I have two reducers. Reducer No.1 : Currently-Selected-Item-Reducer state = {currentlySelectedItemId: 123} Reducer No.2 : All-Items-Reducer state = [{ id: 123, name: "John"}, {id: 231, name: "Jill"}, {id: 411, name: "Alf"}] I have a simple React app and a React component simply displays the currently selected item. I.e., based on the id in the currently-selected-item-reducer , it find the correct item to display in the all-items reducer . Problem: Say the currently selected item is 123 and I want to go to implement a button which will always go the next item in the array. Now I need to

It looks like the Relay store and actions are all classes which aren't serializable which is bummer. But it looks like I ought to be able to separate the cache from the network requests and save the cache in a Flux store. Does that sound interesting or am I barking up the wrong tree? 回答1: Relay can certainly be used alongside Flux, and we've spoken to many developers who are using them together

In response to a state change, I want to trigger another state change. Is that inherently a bad idea? The specific sort of scenario is that the component is modeled as a state machine that renders different information according to the value of this.state.current_state . But external events can prompt it to experience a state transition, via changes to it's state through a flux store. Here's a contrived scenario to get the idea across: I think the correct lifecycle method to do this would be shouldComponentUpdate . Something to this effect: shouldComponentUpdate: function(nextProps, nextState)

I'm tying myself in knots with a React problem which I'm sure can't be as difficult as it seems to me right now. I'm building a single page app against a RESTful server API that returns resources, together with links that describe what can be done with that resource. And I'm trying to ensure that my client's ajax calls only use URLs retrieved from the server in this way. So, for example, my LoggedInSessionStore contains the URL that allows me to fetch the list of all public documents, say. The problem I have is how to manage the dependencies between actions and stores. For example, when the

spring cloud gateway 为了记录访问记录,需要记录请求体里面的内容,但是 request body 是只能读取一次的,如果读取以后不封装回去,则会造成后面的服务无法读取 body 数据. 在网关里添加一个过滤器 RequestRecordFilter 类: @Slf4j @Component public class RequestRecordFilter implements GlobalFilter, Ordered { @Override public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) { ServerHttpRequest request = exchange.getRequest(); URI requestUri = request.getURI(); //只记录 http 请求(包含 https) String schema = requestUri.getScheme(); if ((!"http".equals(schema) && !"https".equals(schema))){ return chain.filter(exchange); } AccessRecord accessRecord = new AccessRecord

And I am getting Dispatch.dispatch(...): Cannot dispatch in the middle of a dispatch. Is there any hack to call action in the middle ? 回答1: I don't see where in the gist that you posted you are doing the redirect. I only see the AUTH_SIGNIN and AUTH_SIGNIN_SUCCESS actions, and they look pretty straightforward. But no, there is no hack to create an action in the middle
